Technological description
A common future direction…
Long Term Evolution (LTE) is a
complementary nextgeneration broadband wireless
technology for all mobile
operators
Robust modulation in dense
environments
OFDM
OFDMA (DL)/SC-FDMA (UL);
Increased spectral efficiency;
Simplified Rx design in UE for high speed data;
Scalable – from 1.4 MHz to 20 MHz carriers
Increased link capacity
MIMO
Multiple-input, multiple-output UL& DL;
Collaborative MIMO (UL);
Overcome multi-path interference
Enabling new applications,
lowering cost
Peer to peer applications
requiring high throughput
Online gaming
Flat fee trend
A taste of 4G…
flat, scalable
Flat IP
Low latency via simpler bearer traffic handling;
Backhaul based on IP / MPLS transport;
Fits with IMS, VoIP, SIP
…based on highly efficient technologies

S-GW is local mobility anchor
PDN-GW is IP anchor for bearers
Terminates (S1-U) interface towards E-UTRAN
Local anchor point for inter-eNB handover and
inter-3GPP mobility
Support ECM-idle mode DL packet buffering
and network-initiated service request
IP routing and forwarding functions
Terminates (SGi) interface towards the PDN
Provides UE IP address management
(allocation)
Provide Policy and Charging Enforcement
Function (PCEF)
Per-SDF based packet filtering
MME controls how UE interacts with the network via NAS signalling
Authenticates UEs and controls access to network connections
Controls attributes of established access (e.g., assignment of network resources)
Maintains EPS Mobility Management (EMM) states for all UE’s to support paging, roaming and handover
Manages ECM (EPS Connection Management) states

Deployment Flexibility:
Complementing CDMA Networks with LTE
CDMA to LTE Seamless Mobility: Value Proposition
CDMA/LTE Seamless Mobility will be critical for a successful LTE deployment
– LTE technology deployment will target high data traffic areas first
– Users will continue to demand uninterrupted coverage
– Interworking LTE with eHRPD (EV-DO) data and 1X voice maximizes ROI on all
assets

EV-DO Network
Evolved HRPD Enables seamless IP mobility between EV-DO and LTE:
Critical for mobile enterprise VPN services and “always on” user services
Interworking LTE with EV-DO via Evolved HRPD (eHRPD)
eHRPD is an enhancement to traditional EV-DO (HRPD) to enable future
seamless IP mobility with LTE based on 3GPP Standards for Evolved Packet
Core (EPC)
Moves the IP mobility anchor out of the Home Agent and into the PDNGateway
Changes from a client-Mobile IP based IP Mobility model to Proxy Mobile IP
y No more foreign agent
y HSGW implements Proxy Mobile IP
y Handset uses Simple IP
Uses EAP-AKA’ for User authentication
y Instead of PAP/CHAP, EAP-AKA’ conforms to 3GPP standards
May optionally include IPv6 support
y Enables larger IP address space for mobiles, and simplifies security
y Supports multiple IP addresses per UE, with combination of IPv6 & IPv4

What about voice?
LTE only for voice and data?
Or LTE data and traditional 3G1x voice?
Factors to consider:
How important is simultaneous voice & data?
How important is an all-IP service model?
CAPEX spending priorities?
Maximize voice capacity?
Roaming Partners?
3G1x CS Voice?
LTE VoIP?
Handset complexity?
Timing?
EV-DO VoIP?

CDMA2000 1X: Best in Class for Voice Capacity
CDMA2000 3G1x voice capacity roadmap
is best in class:
Enables more voice in less spectrum
Maximizes available bandwidth for

Circuit switch fallback – enabling voice
to remain on 3G1x while data is carried
